+Subject: [PATCH] [Build] fix `gRPCConfig.cmake` (#33361)
+
+Without this change, calling `find_package(gRPC REQUIRED)` errors out
+with
+
+CMake Error at /opt/homebrew/lib/cmake/grpc/gRPCConfig.cmake:8
+(find_dependency):
+      Unknown CMake command "find_dependency".
+
+The issue is that `find_dependency` is provided by the
+`CMakeFindDependencyMacro` module[^1], so we need to `include` it before
+use.
